Advantages of having a gryphon php?

[str088]

I have an 04 XLT 5.4l.

The AFE looks like it could have modified the MAF environment, which is a potential source of destructive trouble, but Bill's tunes can compensate for that.

Yeah that's what everyone says, which is why I'm getting a tuner to
counteract it. I see. I've seen some gains from this intake so I don't
really want to replace the old one back in, it actually has a crack on
the box of the airfilter (stock). I've noticed better throttle response.
As far as MPG when I had the stock intake I went 356 miles, and the
afe took me to 382. I drive pretty consistently so I love the difference
that it has given me. But thanks for giving me a break down for stock
intake. I appreciate it. I just always thought it looked pretty restrictive
with all those chambers.

The passing performance was greatly improved and I am certain I've gained in the fuel economy area. The "feeling of power" is a bit more subjective, but I think I've gained there too.

That's exactly what I was looking for, I wanted a little more gain in the
mpg. I know the power is not really reliable because anyone who buys
something expects to see some improvement so they do "see it" if that
makes sense. Like the placebo effect. But one could speculate that there
will be some gain "power" wise.

Okay, I'll stop editing my posts. I just didn't want to keep on putting
new posts, so I just added on.

I was thinking of that, but I regularly put in 89 myself. I know it's not
necessarily better gas I just wanted a little more oomph you could say
when I accelerate. I ordered 91 because at the bottom of the gryphon
php page I got confused with the red paragraph saying it's better to get
87 and 91 instead of 89 and 91. So I thought that they were saying that
I shouldn't get the same octane for both custom tunes or I'd be wasting
my money kind of thing.

I know my motorcycle can't get anything lower than 91 because it would
put too much wear on my engine. 01 CBR. I didn't realy know that but
you learn something new. I actually thought they just burned easier.

Thanks Jack for your input and information it is invaluable to me and
appreciate the time you put into replying to me.

Just to add on to Jack's posts, I also noticed a distinct upgrade to the power during passing. Also the quickness of the shifts on top of the extra hp makes me hate going back to stock!
I have an 05 XLT with the 5.4 just for reference.
Also the 89 octane, if the engine isn't tuned for it, really can't provide more oomph. It also won't help in gas mileage for the same reasons as power.
How it works is that the octane makes it burn slower under the same pressure, or burn at the same rate under higher pressure. This is an advantage in high compression motors, such as your motorcycle, or most racing engines, but in our trucks it isnt necessary, and they can't take advantage of it without tuning. With some octanes, I dont think 89 is far enough off of what our trucks are designed for, it can actually hurt gas mileage and power because it burns too slow. this could possibly leave unburned gas in the cylinder which would then exit out the exhaust and possibly causing backfires or in racing motors that cool blue fire .
Hope I helped you and everyone understand more , and if I am wrong, feel free to correct me!

I see. Well good thing I don't use premium then =) That is very informative and
thanks for it. I'm sure 89 is just fine for the tank and hopefully since the tuner
will be programmed for 89 I'll get that gain from using a higher octane level. I do
want to get some kind of gain especially in passing, acceleration, and a little more
hp. This is the first Ford I've ever owned and I'm impressed. I guess it might be be-
cause of my bike, but I just want a little more response and speed in my truck. Not
that I want my truck to be as quick (pretty sure that's impossible unless I spend an
arm and a leg) but I want there to be more power when I need it I guess you could
say.

Better drivablity and the seat of your pants dyno agrees too.....

Sounds good. I'm very excited about the programmer and the new tunes.
